Abstract
A leak fuel collection apparatus of the internal combustion engine using leak oil collection pipe fuel is provided, by which the improvement in fuel consumption and exhaust emission can be achieved by improving the combustion condition of the leak fuel mixed with fresh air in the cylinder in correspondence with the engine operating conditions.The leak oil collection pipe is connected to the intake air pipe of the engine, a leak pipe open/close valve is provided to the leak oil collection pipe for opening or closing the leak pipe, and the leak pipe open/close valve is opened when the engine load at an engine rotation speed exceeds a predetermined value determined for the rotation speed and is closed when the engine load at said rotation speed is equal to or lower than said predetermined value.
